More likely Samsung see the value in the idea and therefore think it's a useful* thing to add to their handsets. Because all it does is reproduce the well-established historical look of tickets on a digital screen they don't see any IP hurdle to including it.
I don't like the copying debate because it sort of endorses the idea that there's necessarily always something wrong in copying — that if any feature of your product has any close antecedent then you've no right to claim creativity. In this case it's clear that the Apple feature has inspired the Samsung but I don't see that there's anything wrong with that, especially if Samsung end up doing it better. On a technical level, Apple's implementation is very lacking as every app that wants to put something into the passbook has to push it there, which in most apps means making your booking then digging through submenus to find the 'put into Passbook' option. If I've booked something in a compatible app, the pass should just be there in the Passbook; I shouldn't have to think about whether it's pushed or pulled and I definitely shouldn't have to do anything manually.
